Lamp shade



M. STADLER LAMP SHADE Filed Aug. 25, 1935 INVENOR.

Patented Apr. 21, 1936 UNITED STATES PATENT oFIcE 4 Claims.

This invention relates to lamp shades, of the type principally used forfloor, table, or kindred lamps, and its object is to provide a shadewhich is conveniently and economically manufacturable, economicallysalable, strong, durable, and improved.

Heretofore, such lamp shades comprised a framing having upper and lowerrings, to the former of which one side of the covering was secured byhand sewing, and then the covering was stretched over the framing andits opposite side similarly sewed to the lower ring, which method istime-consuming, costly, and generally unsatisfactory. Another object ofmy invention is to provide a shade which will eliminate thesedisadvantages.

Other objects and advantages will hereinafter appear.

In the accompanying drawing,

Fig, 1 is a perspective View showing the covering of the lamp shade, asused in this invention.

Fig. 2 is an elevation of the framing of the lamp shade, used for thisinvention.

Fig. 3 is a fragmentary cross-sectional elevation, in an enlarged scale,of the shade covering shown in Fig. 1, taken on the line 3-3.

Fig. 4. is a fragmentary cross-sectional elevavation, showing the lampshade in completely assembled state.

Fig. 5 is a fragmentary cross-sectional elevation, showing amodification of the invention.

The framing i, Fig. 2, of the lamp shade 2, Fig. 4, comprises an upperring 3 of fiat metal, a lower ring 4 of flat metal, and a plurality ofupright supports 5 which join said rings by their terminals fitting insockets 6 that are in turn secured to the rings. The supports 5 are madeof springy flexible material, the function of which will be hereinaftershown.

The covering l, Figs. 1, 3, of the lamp shade comprises the usual clothsheet 8, to and along the upper and lower edges 9 of which are securedtubes l0 made of any strong fabric or other suitable material, andthrough said tubes are passed and inserted split hoop bands I l made ofspringy flexible metal or other suitable material.

When assembling the lamp shade 2, the covering 'l' is enveloped over theframing l, and the upper tube Ill with its internal band H are then bentover, within, and against the inner side of the ring 3 of the framing,in the manner shown in Fig. 4. Thereafter the lower tube ill with itsinternal band H are similarly bent under, within, and against the innerside of the ring l of the framing I, and thereupon the lamp shadebecomes completed, presenting the usual required appearance with thecovering material 8 in taut state.

During the assemblage of the lower tube In and its band H with the lowerring 4 of the framing, the upward exertion upon the said band incidentto the operation causes the flexible supports 5 to bend and facilitatethe assembling, and upon completion of the latter the supports 5 springback to straightened condition and thereby impart improved tautness tothe covering material 8. Any desired cloth lining sheet l2 may beprovided for the interior of the lamp shade, by stitching it at I3 tothe upper and lower tubes In, as shown in Fig. 4. If desired, rivets l4may be passed through the tubes l0, bands II, and ring 3 or 4, to impartadditional security to the assemblage of these parts, as illustrated inFig. 5.

Variations may be resorted to within the scope of the invention, andportions of the improvements may be used without others.

Having thus described my invention, I claim:-

1. A lamp shade having the combination of a framing, said framing havingan upper ring and a lower ring, a plurality of springy flexible uprightsjoining said rings, a covering for the shade having a tubular portionalong its upper edge and a tubular portion along its lower edge, aflexibleband passing through each of said tubular portions, and saidcovering being mounted over said framing by said upper tubular portionwith its band folding over and against the inner side of said upper ringand said lower tubular portion with its band folding under and againstthe inner side of said lower ring.

2. A lamp shade having the combination of a framing, said framing havingan upper ring and a lower ring, a covering for the shade having atubular portion along its upper edge and a tubular portion along itslower edge, a flexible band passing through each of said tubularportions, and said covering being mounted over said framing by saidupper tubular portion with its band folding over and against the innerside of said upper ring and said lower tubular portion with its bandfolding under and against the inner side of said lower ring.

3. A lamp shade having the combination of a framing, said framing havingan upper flat metal ring and a lower fiat metal ring, a plurality ofspringy flexible uprights joining said rings, a covering for the shade,a fiat metal band secured to and along the upper edge of said covering,a fiat metal band secured to and along the lower edge of said covering,and said covering being mounted over said framing by said upper bandbeing positioned against and entirely within the inner side of saidupper ring and said lower band being positioned against and entirelywithin the inner side of said lower ring.

4. A lamp shade having the combination of a framing, said framing havingan upper ring and a. lower ring, a covering for the shade, a bandsecured to and along the upper edge of said covering, a band secured toand along the lower edge of said covering, and said covering beingmounted over said framing by said upper band being positioned againstand entirely within the inner side of said upper ring and said lowerband being positioned against and entirely within the inner side of saidlower ring.
